Clean the Petromax Dutch oven ft6 after each use only with warm water and a dish brush or chainmail scrubber, without using grease-cutting detergent, to preserve the protective patina. Dry the pot thoroughly afterwards (briefly on a heat source if necessary) and apply a thin layer of Petromax care paste or a heat-resistant neutral oil for maintenance. Store the Dutch oven in a dry place with the lid slightly ajar to allow for air circulation.
